BESS Degradation capacity and power

Dear  All and Paul, 
I have a question regarding degradation behavior of a Battery (LFP) in a PV-plus-Storage system. In this configuration, the battery cycle is generally constant as the batttery charge from the pv system and discharge at the begining of the night. (Charging from the grid is not allowed in this case). 

I looked on "Data Tables" to check how the capacity and power is degrading but I only see a degradation on total Capacity (MWh). From my understanding, if we have a battery bank of X Power (kW) and Y Capacity (MWh), degradation will have an effect on both factors because of the acumulation of internal resistans on battery cells (X-X*d1 and Y-Y*d2). Does SAM neglect this effect? 
I Attached a summarized table (from data Table) and SAM file.

 






 

Thanks Paul for your reply, 

From the comment on github, I see that the resistance is set as a constant value in Battery SAM model . Is it possible to see the effect on  Maximum Power output with an increase in interal resistance?

From my understanding the limitation on Power will be determinated with (1) C-Rate of the cell and (2) their PCS (power converter system) where are conected. 

Look forward to your reply 
Kind Regards !
